Book Description
Over the last two‑plus decades, the scientific validity of the principles that underpin identifying a firearm from recovered fired ammunition has been a core issue for the admissibility of expert evidence in criminal trials in the United States. The issues that dominated the determinative points, as they related to the scientific and technological analysis, centered around the following: the validity of uniqueness of firearms, subjective methodology, the potential rate of error, unknown statistical certainty and unsatisfactory proficiency tests. These issues have essentially become the legal requirement for admissibility of experts' opinion on the linkage of firearms with fired ammunition, an important forensic opinion that connects the crime with the perpetrator through the weapon of offence. In Forensic Firearms in Criminal Trials: Legal, Investigative, and Scientific Aspects, internationally renowned forensic firearm expert Dr J. K. Sinha provides demonstrative explanations and helpful clarifications using simple illustrative examples from scientific casework and everyday life. The goals are to: Prove the scientific validity of the uniqueness of identifying features of firearms Identify the statistical threshold to qualify and determine a corresponding match Debunk the misconception of subjective methodology and the potential rate of error thereof in experts' decision making and opinions Clarify the prevailing perception of similar, dissimilar and insufficient marks and consequential interpretation With certain non‑technical readers in mind as well, the book provides a basic understanding of the general make‑up of firearms and ammunition, the evidentiary values of commonly used firearms, fired empties, fired bullets and pellets, and scientific investigative leads that result from visual and physical evidence. Chapters cover related topics such as proficiency tests, identifying competent experts, admitted firing, and reliable and testable methodology. The book also reviews the admissibility of expert evidence in India and explains the proviso of admissibility of ballistic expert report in criminal trials. Throughout, the author emphasizes the need for requisite forensic knowledge by the investigator and aided by a competent expert for effective scientific investigation of gunfire crimes such as would aid in the proper presentation of scientific evidence at criminal trial for a successful outcome.

Book Description
In recent years, the use of illegally produced firearms has increased exponentially worldwide. These are often cheap, nonstandard firearms that defy known classification and identification criteria. The use of unusual firearms in crimes has frequently led to unpredictable and misleading reconstruction of shooting incidents. In this book, internationally known forensic firearm expert, J.K. Sinha, presents a detailed forensic study of unusual firearms, with the goal of helping crime-scene investigators to minimize erroneous conclusions in cases where these types of firearms are used. Based on his extensive experimentation with more than 1,000 nonstandard firearms, the author identifies new class characteristic parameters needed to establish linkage of projectiles with irregular rifled and smoothbore barrels. The book begins with an introduction to unusual firearms and proceeds to discuss forensic investigation of fired bullets, medico-legal evidence, barrel marks on fired shots, and investigation of fired cartridges and shot charge. Chapters also cover topics such as timing of firing, unusual rifling marks, shooter identification, and unusual bullet hole evaluations. Providing concise yet complete techniques for making forensic analyses and conclusions, this is the first book of its kind to critically examine the use of unusual, nonstandard firearms in perpetrating crimes. It is intended for professionals and academicians working in the field: forensic firearm experts and consultants, forensic medicine professionals and medico-legal experts, prosecution and defense attorneys, enforcement agencies and judiciary, university students and researchers studying forensic science, forensic medicine, criminology and law.

Book Description
Battlefield Forensics for Persian Gulf States provides an illustrative reference of various weapons, toolmarks, headstamps, and other traits in order to identify the origins of a variety of guns, casings, and ammunition that can be found in the Middle East. Various conflicts in the region have led to innumerable weapons being used throughout the years. The lead author, Don Mikko, has investigated and examined firearms related items of evidence in countless crime scenes throughout the world. As the Chief of the Firearms Branch at the United States Army Criminal Investigation Laboratory (USACIL), Fort Gillem, Georgia, he recruited, trained, and competency tested military contractors deploying to various combat related areas of the world, those providing forensic firearm and toolmark identification support to local commanders. What was learned was that various foreign weapons and ammunition were being utilized in conflicts and by opposing forces. This book educates readers on the technical data for different types of firearms, ammunition, countries of origin, proof marks, penetrator information and the typical firearm markings imparted on fired cartridge cases, such as breech-face, firing pin, ejector, and extractor markings. Forensics and biometrics within the Persian Gulf have been leveraged since the early 1990s and many of the firearms and types of ammunition covered in this handbook are addressed in an effort to assist those on the ground who are required to be able to identify such items in various scenarios. The information contained within the book has proven to be effective on the battlefield and has helped shape combat operations. This handbook will serve as a useful reference not only to assist military and contractor personnel within the various combat locations but will also prove to be beneficial for law-enforcement, crime laboratory personnel, forensic firearm and toolmark examiners, crime scene investigators, students, practitioners, and civilian personnel throughout the world.
